SELF-*THREADING LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 630,051, dated August1, 1899.

Application filed March 24, 1899. Serial No. 710,285, (No model.)

To all whom it may concern.-

Be it known that I, STEPHEN M. HAMBLIN, a citizen of the United States,residing at Oentral Falls, in the county of Providence and State ofRhode Island, haveinvented certain new and useful Improvements inSelf-Threading Loom-Shuttles, of which the following is a specification,reference being had therein to the accompanying drawings.

to In the said drawings, Figure 1 is a plan of portion of a loom-shuttleembodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is aplan of the educt-tube, the latter being shown separately. Fig. 4 is anend elevation thereof. Fig. 5 is an inverted or bottom View thereof.Fig. 6 is a view thereof, looking from the left-hand side in the otherfigures.

1 designates the body of a loom-shuttle; 2,

2c the spindle thereof; 3, a cop on the said spindle; 4, a yarn-passagein the forward portion of the shuttle-body in line with the saidspindle, and 5 the threading-chamber, which is formed in the shLittle-body at the forward end 2 5 of the said yarn-passage 4.

6 designates a depression which I form in the upper side of the forwardportion of the shuttle -body in advance of the threadingchamber 5, thesaid depression constituting a 0 continuation or extension of the saidthreading-chamber and having an inclined bottom which slopes upwardlyand forwardly from the threading-chamber, as is indicated clearly indotted lines in Fig. 2.

3 5 7 designates the educt-tube. It is inserted in the delivery-eye ofthe shuttle, as shown in Figs. 1 and 2, and its length extendstransversely across the shuttle. Its inner end is in line with the axisof the shuttle-body and spin- 0 dle, so that the yarn paying off fromthe cop upon the spindle leads around the said inner end in traveling onits way through the educttube, the said inner end of the educt-tubeserving as a means of guiding the yarn from 5 the spindle and enablingit to change its direction of movement. A threading-slit 8 ex tends fromone end of the educt-tube to the other. From the upper side of thatportion of the educt-tube which projects inwardly into threading-chamber5-that is to say, from the upper edge of the threading-slit Sathreading-tongue 9 extends forwardly into the depression 6. Theextremity of the said threading-tongue 9 lies near the sloping bottom ofthe said chamber 5, with usually a slight upward bend at its tip tofacilitate the operation of introducing the yarn under the said tip inthreading the shuttle. The for ward extremity of the saidthreading-tongue 9 crosses the continuation of the axis of the spindle.In the operation of threading as the yarn is drawn by hand forward offthe spindle lengthwise of the shuttle it is at the same time moved sothat it shall be carried downward into the passage 4, chamber 5, anddepression 6. The yarn in consequence of being simultaneously advancedand depressed will travel along the inner side edge of the said tongueand be deflected thereby until it drops off the end of the tongue,whereupon it will pass under the laterally-projecting tip of the tongue,thus assisting in getting the yarn under the tongue. The outer edge ofthe tongue 9 inclines outwardly from its tip to its base, being formedwith an easy compound curve in the illustrated embodiment of theinvention. The said edge is located so that it terinmates at thebeginning of-a slit formed in the shuttle-body and communicating withthe delivery-eye, the said slit having the vertical 8o portion 10extending diagonally across the outer part of the shuttle-body from thecha1nher 5 to the outer face of the shuttle-body and downward to thelevel of the delivery-eye and the horizontal portion 11 intersectingboth the 8 said vertical portion and also the deliveryeye. The slit 8 iscarried around to the upper side of the ed net-tube 7, in the outerportion of the latter, so that the outer end of the said slit 8 isconvenient of access from the said horizontal portion 11 of the slit inthe shuttle-body.

In threading the shuttle after the yarn has been drawn forward andcaught under the tip of the threading-tongue 9 in the manner which hasbeen described already the portion of the yarn which is held in the handof the weaver is carried rearwardly along the outer edge of the tongue 9and also along the rearwardly-extending diagonal slit 10 in the shutzootie-body. It next is depressed to carry it down in the slit 10 into thehorizontal slit 11.

the interior of the said educt-tube.

12 12 designate inwardly-extending lips or spurs which are provided atopposite sides of the outer end of slit 8 in educt-tube 7. These lips orspurs are separated from each other widely enough to permit the yarn topass freely between the same in the operation of threading; but it ispractically impossible for the yarn to find its way out between themagain unless purposely aided by the hand of the weaver. In some cases asingle lip or spur may be used. For the purpose of securing theeduct-tube in place, it is provided with a projecting ear or lug 13,suitably formed upon or secured to the same and having a hole 131therethrough, through which hole is passed a securing-screw 14, by meansofv which the said ear or lug is clamped against a shoulder or ledge 15at the bottom of the chamber 5.

I claim as my invention- 1. The combination with a shuttle-body having adelivery-eye extending through one side thereof and a threading-slitcommunicating with the said eye, of the educt-tube extendingtransversely of the shuttle withits outer portion cylindrical andlocated in the said delivery-eye, the said tube having thethreading-slit which is reached through the said slit in theshuttle-body and also having the threading-"tongue projecting forwardlyfrom the inner portion of the same from the upper edge of theinner endof the slit in the tube and terminating at the beginning of the slit inthe shuttle-bod y, substantially as described.

2. The combination with a shuttle-body having a delivery-eye extendingthrough one side thereof and a threading-slit communicating with thesaid eye, of the educt-tube extending transversely of the shuttle withits outer portion located in the said delivery-eye, the said tube havingthe threading-slit which is reached through the said slit in theshuttlebody and also having the threading-tongue projecting from theinner portion of the same above the inner end of the slit in the tube,and the inwardly-projecting lips or spurs at the outer end of the saidslit to prevent escape of the yarn from the interior of the tube,substantially as described.

3. The combination with a shuttle-body having a delivery-eye extendingthrough one side thereof, a threading-slit communicating with the saideye, and a depression, as 6, of the educt-tube extending transverselyofthe shuttle with its outer portion cylindrical and located in the saiddelivery-eye, the said tube having the threading-slit which is reachedthrough the said slit in the shuttle-body, and also having thethreading-tongue extending from the upper edge of the inner portion ofthe same above the inner end of the slit in the tube and projectinginto. the said depression with its tip adjacent the bottom of the latterand terminating at the beginning of the slit in the shuttle-body,substantially as described.

4. The educt-tube formed with the threading-slit, the tongue extendingfrom the inner portion of the same above the inner end of the said slit,and one or more inwardly-projecting lips or spurs at the outer end ofthe said slit, substantially as described.

5. The combination with a shuttle-body having a delivery-eye extendingthrough the side thereof, a threading-chamber, avertical slit extendingdownward as Well as diagonally backward and outward from the saidchamber to the exterior of the shuttle-body, and a horizontal slitintersecting both the said vertical slit and the delivery-eye, of theeduct-tube with its outer end located inthe said delivery-eye and havingthe threadingslit and the threading-tongue extending from its upper sideabove the inner end of the said threading-slit, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

STEPHEN M. HAMBLIN.
